Four of the fatalities occurred in Smithfield, New York, according to the Associated Press.

The small town, roughly 25 miles northeast of Poughkeepsie, also reported three collapsed homes, two of which were entirely destroyed. No tornado has been confirmed by the National Weather Service for the area, though damage assessment will continue.

A young boy was killed by a falling tree at a summer camp in Manchester, Maryland, on Tuesday night. According to the River Valley Ranch Facebook page, the camp staff began ushering campers to a more secure building once the storms approached the area, which is located just south of the Pennsylvania border.

Trees and branches began falling before all of the campers made it into the building, injuring eight and causing one fatality.

Storms swept through areas of New York, Pennsylvania, Maryland, Ohio, West Virginia and even caused damage as far south as Virginia. There were widespread reports of roads blocked by trees, damaged homes and high winds.

Nearly 100,000 people were without power in Pennsylvania and more than 86,000 in West Virginia.

Philadelphia experienced widespread power outages, which Senior AccuWeather Meteorologist Elliot Abrams said were caused by a microburst. When thunderstorms ramp up and bring high winds, a sudden drop of wind can push towards the ground and spread out upon impact.

Abrams likens the phenomenon to a bowling alley; the ball is the wind that travels down a narrow path and the pins are the trees that fall to the ground upon being struck.

"A bowling ball of high winds smashed though the area, flattening trees like toothpicks and snapping power lines," Abrams said of Tuesday's microburst.
